proteolysis

Serine endopeptidases are a class of proteases that use an active-site serine residue as the nucleophile to hydrolyze peptide bonds within proteins or polypeptides. Their members participate in protein digestion, coagulation and fibrinolysis, complement activation, inflammatory regulation, ...

The uPA/uPAR system is not merely a proteolytic module, but an important interface linking local fibrinolytic activation, cell-adhesion switching, amplification of migratory signaling, and microenvironment remodeling.

Bromelain is a class of thiol protease (cysteine protease) mixtures primarily derived from pineapple juice, peel, and stem tissues. It is typically a pale yellow to light brown amorphous powder with a slight characteristic odor, and an approximate molecular weight on the order of 3.3 × 10^4.
